Antibiotic Release from Biodegradable PHBV Microparticles

Journal of Controlled Release, 1998
For the treatment of periodontal diseases, design of a controlled release system seemed very appropriate for an effective, long term result. In this study a novel, biodegradable microbial polyester, poly(3-hydroxybutyrate-co-3-hydroxyvalerate), PHBV of various valerate contents containing a well established antibiotic, tetracycline, known to be ...

Electrospun PVP-Core/PHBV-Shell Fibers to Eliminate Tailing Off for an Improved Sustained Release of Curcumin.

Molecular Pharmaceutics, 2021
Tailing off release in the sustained release of water-insoluble curcumin (Cur) is a significant challenge in the drug delivery system. As a novel solution, core-shell nanodrug containers have aroused many interests due to their potential improvement in ...

Extrusion foaming of PHBV

Journal of Cellular Plastics, 2014
This paper reports work on extrusion foaming of poly(3-hydroxybutyrate- co-3-hydroxyvalerate) with a chemical blowing agent based on sodium bicarbonate and citric acid and calcium carbonate nucleation agent. It includes investigations in the effects of rheological behaviour of the polymer, blowing agent, nucleation agent and processing conditions on ...

Development of a layered bacterial nanocellulose-PHBV composite for food packaging.

The Journal of the Science of Food and Agriculture, 2022
Most of the current materials used in food packaging are synthetic and non-degradable, raising environmental issues derived from the accumulation of plastics in landfills/waterways.

Genetic network driven control of PHBV copolymer composition

Journal of Biotechnology, 2006
We developed a detailed mathematical model describing the coupling between the molecular weight distribution dynamics of poly(3-hydroxybutyrate-co-3hydroxyvalerate) (PHBV) copolymer chains with those of hydroxybutyrate (HB) and hydroxyvalerate (HV) monomer formation.

Effect of PHBV‐g‐MA compatibilizer on the properties of poly(3‐hydroxybutyrate‐co‐3‐hydroxyvalerate)/polylactide blend/Diss fibers biocomposites

Journal of Polymer Science
This study investigates the morphology and properties of biocomposites based on a blend of poly(3‐hydroxybutyrate‐co‐3‐hydroxyvalerate) (PHBV) and poly (lactic acid) (PLA) 50/50 (w/w) reinforced with untreated (UNDF) and alkali‐treated (ATDF) Diss ...

Tissue engineered cartilage on collagen and PHBV matrices

Biomaterials, 2005
Cartilage engineering is a very novel approach to tissue repair through use of implants. Matrices of collagen containing calcium phosphate (CaP-Gelfix), and matrices of poly(3-hydroxybutyric acid-co-3-hydroxyvaleric acid) (PHBV) were produced to create a cartilage via tissue engineering.

Novel Self‐Reinforced Films Based on Poly (3‐Hydroxybutyrate‐Co‐3‐Hydroxyvalerate) (PHBV) and PHBV Microparticles

Polymer Engineering & Science, 2018
Biodegradable self‐reinforced films of poly (3‐hydroxybutyrate‐co‐3‐hydroxyvalerate) (PHBV) and PHBV microparticles were prepared through the solvent casting method (srPHBV). Differential scanning calorimetry (DSC), wide angle X‐ray scattering (WAXS) and polarized optical microscopy results confirmed the nucleating effect of PHBV microparticles.

Interaction of human smooth muscle cells on random and aligned nanofibrous scaffolds of PHBV and PHBV-gelatin

International Journal of Polymeric Materials and Polymeric Biomaterials, 2016
ABSTRACTTissue-engineered scaffolds with nanofibrous morphology have been shown to be effective in regeneration of tissues because nanofibers mimic the native architecture of the extracellular matrix. The unique alignment in the native tissue motivated the authors to fabricate aligned nanofibers of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV ...
